Synthesis of complete orthonormal fractional basis functions with prescribed poles
(IEEE-Inst Electrical Electronics Engineers Inc, 2008)In this paper, fractional orthonormal basis functions that generalize the well-known fixed pole rational basis functions are synthesized. For a range of noninteger differentiation orders and under mild restrictions on the ... -
An insight into instrumental variable frequency-domain subspace identification
